Productivity Challenge

960 observing hours per year

160 observing flights per year

Variety of instruments

Large community of observers

Conclusion: The traditional “PI” approach is unworkable. A new system for efficiency and relentless observation is needed.

The DCS Mission

The DCS shall provide the infrastructure to support the operation of facility instruments on SOFIA using best current knowledge and tools, and supporting continuous improvement in an efficient, extensible, and modular architecture.
